MEANS FOR SUSPENDING OUTBOARD MOTORS FROM BOATS.

Specification of Letters Patent.

Patented Dec. 28,1915.

Original application filed March 3, l9l3, Serial No. 751,696. Divided and this application filed July 6,

' ance with the present invention is characterized mainly by the fact that the motor.

is mounted in sleeves or the like, which sur-,

round the motor cylinder and, as the case may be, a part connected withit or (where there are several cylinders) the motor cylinders (two or more of them), so that, if the propeller connected with the motor or an adjacent part runs aground, the motor shafts swings away, whereby it, and other parts as well, escape being damaged. This device, moreover, renders it possible that the propeller shaft can be easily and conveniently adjusted in a suitable direction. The

motor mav be suitably suspended by the aid.

of clamping means fixed to the boat.

The invention is more particularly adapted for use in connection with motors of the type disclosed in our (re-pending application, Serial Number 751696, liled March 3, 1913, of which the present application is a division.

We have illustratively exemplified our invention in the accompanying drawings, wherein-- Figure 1 is a front elevational view of our improved suspension means with a motor in position therein; Fig. 2 is a side clevational view, a fragment of the boat being shown in section; Fig. 3 is a, fragmentary side elevational view of a modified form in which the motors locked to the boat by the aid of bolts; tend Fig. 4. is a further modified form wherein a divided motor shaft is shown.

In the suspension device illustrated the motor cylinders hare embraced by clamping sleeves 22, 'i'g'omgthc lower parts of which depend arms 'iil, formed at their lower ends into bars 24, adapted to be inserted into sockets 25,, which are formed in a plate 26 fixed on the stern of the boat. The bars 2 1 may be held at different positions in the sockets by means of set screws whereby the Serial No. 849,349. I I

vertical position of the motor and the propeller can be regulated according to the height of the boat. The upper parts of the clamping sleeves 22 are niovablyi connected with; the lower parts by means of hinges 27 and, when the clamping sleevesfembrace the cylinders, the parts of the sleeves are connected together by means of the usual nut and bolt connection 28, which acts on the upper parts of the sleeves. By means of the nuts 28 the friction between the clamping sleeves and the cylinders can be regulated; it should be so regulated that the motive force developed by the propeller is transmitted to the boat through the motor, the clamping sleeves and the arms 23, and the sleeves 22 should not be clamped too tightly to prevent the shaft from swinging backwardly in case the boat runs aground, or ,the propeller meets with a substantial obstruction. In order to obtain sufficient friction the contact surfaces of the cylinders and clamping sleeves may be milled, or roughened in some other way, or made V- shaped.

From a fixed part of the motor, 0. g. the crank casing 29 common to the two cylinders, project arms or lugs 30, from which depend rods 31, which are connected to a. sleeve 32 surrounding the motor shaft, the connection being preferably eliected with the aid of a sleeve or ring 33, embracing the sleeve 32. By this arrangement the whole driving apparatus is braced.

If desired, the motor may be locked in adjusted position to the boat, so that it cannot turn after adjustment. For this purpose the bolts which connect the upper ends of the brace rods 31 with the lugs 30, may pass through openings in arms 34, which are mounted on the boat or the mounting plate 26. This construction is shown in Fig. 3. The openings in the arms 34 are elongated, whereby the adjustment of the motor shaft is rendered possible.

To enable the motor and propeller to be adjusted according to different heights 'of stern in different beats, it should be possible for them to be fixed to a boat so that they may be raised and lowered. For this purpose the sockets 25 may be provided with set screws (see Fig. 2) taking against the bars 24, which can, thus be securely held at the desired position in the sockets.

In the driving apparatus shown in Fig. 4,

the transmission of power from the motor to the propeller shaft is effected by means of two vertical shafts (one of which is the motor shaft) connected with each other by means of a gearing 35. This arrangement is intended especially for the case when the motor is running at a speed which must be converted to another speed, more suitable for the propeller. In Fig. 4 the sleeves 22, or their arms 23, are shown as being secured directly to the boat.

Having thus described our invention What we claim as new and desire to secure by Letters Patent is 1. In combination, a motor having oppositely extending cylinders substantially coaxial with each other, an adjustable sleeve embracing each cylinder, and means for attaching said sleeves to a boat.

2. In combination, a motor having oppositely extending and substantially co-axial cylinders, a sleeve embracing and supporting each cylinder, a sleeve surrounding the motor shaft, and braces extending from fixed parts of the motor to the last named sleeve.

3. In combination, a motor having oppositely extending and substantially co-axial cylinders, a sleeve embracing and supporting each cylinder, a propeller shaft, and a transmission between the motor and the propeller shafQ said transmission comprising two shafts and a gearing between them.

In witness whereof we have hereunto set our hands in presence of two witnesses.
